Chemistry in Daily Life
Introduction
Chemistry: Chemistry is the science of matter, especially its chemical reactions, but also its
composition,
structure
and
properties.

Daily
Life:
All
the
things
that
happen
or
that
you
do
regularly.
Chemistry in Daily Life: Chemistry is a big part of our everyday life. We find chemistry in daily
life in the foods we eat, the air we breathe, our soap, our emotions and literally every object we
can see or touch. Here's a look at some everyday chemistry. [pic]
Actually, we found chemistry every were in our daily life, in every sector of our life.
Importance
of
Chemistry:
Chemistry is important in everyday life because everything is made of chemicals. You are made
of chemicals. Many of the changes you observe in the world around you are caused by chemical
reactions. Examples include changing colors of leaves, cooking food and getting clean.
Breathing:
Breathing is chemistry, because plants create oxygen through photosynthesis using carbon
dioxide that humans exhale. Every moment we take breath for live. So, Chemistry uses our daily
life.
Drug:
Behind every drug there is utilization of mixed chemicals so present man can not lead life
without
drug
that
is
miracle
of
chemistry.
Chemistry
in
Household
Work
Chemistry can found every were so Chemistry use in our house. We use Chemistry in every
work,
what
we
do
in
our
life.
Home
needs:
Plastics:
All home needs like plastics(mugs,buckets,polythene covers,bags,comb.....etc) which made by
the
use
of
Chemistry.
Glass:
In daily life glass is used for a variety of purposes, the glass is used for making window panes,
bulbs
&tumblers
in
soda
glass.
Soaps:
[pic]
Soaps are the detergents used since long. Soaps used for cleaning purpose are sodium or
potassium salts of long chain fatty acids, e.g., stearic, oleic and palmitic acids. Soaps containing
sodium salts are formed by heating fat (i.e., glyceryl ester of fatty acid) with aqueous sodium
hydroxide
solution.
This
reaction
is
known
as
saponification.
Chemistry
for
washing:
Chemicals make our clothes clean. Not only clothes but we also use chemicals to wash utensils.
So
many
kinds
of
detergent
made
by
using
chemistry.
Synthetic detergents are mainly classified into three categories: i) Anionic detergents (ii)
Cationic
detergents
and
(iii)
Non-ionic
detergents
This
kind
Chemistry
of
detergents
we
use
Use
in
our
in
daily
life.
Food
Chemicals are added to food for (i) their preservation, (ii) enhancing their appeal, and (iii)
adding nutritive value in them. Main categories of food additives are as follows:
(i)
(ii)
(iii)
(iv)Flour
Food
Flavors
Fat
emulsifiers
improvers
–
ant
and
and
staling
stabilizing
agents
and
colors
sweeteners
agents
bleaches
(v)
Antioxidants
(vi)Preservatives
vii) Nutritional supplements such as minerals, vitamins and amino acids. Except for chemicals of
category
(vii) None of the above additives have nutritive value. These are added either to increase the
shelf life of stored food or for cosmetic purposes. In this section we will discuss only food
preservatives.
Food preservatives: Food preservatives prevent spoilage of food due to microbial growth.
Preservatives The most commonly used preservatives include table salt, sugar, vegetable oils
and sodium benzoate, C6H5COONa. Sodium benzoate is used in limited quantities and is
metabolized in the body. Salts of sorbic acid and propanoic acid are also used as preservatives.
Summary
Chemistry is essentially the study of materials and the development of new materials for the
betterment of humanity. A drug is a chemical agent, which affects human metabolism and
provides cure from ailment. If taken in doses higher than recommended, these may have
poisonous effect. Use of chemicals for therapeutic effect is called chemotherapy. Drugs usually
interact with biological macromolecules such as carbohydrates, proteins, lipids and nucleic
acids. These are called target molecules. Drugs are designed to interact with specific targets so
that these have the least chance of affecting other targets. This minimizes the side effects and
localizes the action of the drug. Drug chemistry centers on arresting microbes/destroying
microbes,
preventing
the
body
from
various infectious diseases, releasing mental stress, etc. Thus, drugs like analgesics, antibiotics,
antiseptics, disinfectants, antacids and tranquilizers are used for specific purpose. To check the
population explosion, ant fertility drugs have also become prominent in our life. Food additives
such as preservatives, sweetening agents, flavors, antioxidants, edible colors and nutritional
supplements are added to the food to make it attractive, palatable and add nutritive value.
Preservatives are added to the food to prevent spoilage due to microbial growth. Artificial
sweeteners are used by those who need to check the calorie intake or are diabetic and want to
avoid taking sucrose. These days, detergents are much in vogue and get preference over soaps
because they work even in hard water. Synthetic detergents are classified into three main
categories, namely: anionic, cationic and non-ionic, and each category has its specific uses.
Detergents with straight chain of hydrocarbons are preferred over branched chain as the latter
are non-biodegradable and consequently cause environmental pollution.
